GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 972) = 63180
GCD(390, 972) = ( 390 x 972 ) / 63180
= 390 / 972
= 390
Step2:
LCM(6, 858) = 858
GCD(6, 858) = ( 6 x 858 ) / 858
= 6 / 858
= 6
Step3:
LCM(6, 332) = 996
GCD(6, 332) = ( 6 x 332 ) / 996
= 6 / 332
= 6
So, Greatest Common Divisor of 390, 972, 858, 332 is 2
